Jay Fiedler, after five seasons with the Dolphins, is no longer the enemy.

“It’ll be nice to come out there and hear the cheers and know they’re for the uniform that I’m wearing in Giants Stadium,” Fiedler said. “But my focus is gonna be between the lines. I don’t know how it’s gonna feel to be honest with you.”

Fiedler, with Chad Pennington sitting out, will start for the Jets in tonight’s preseason opener against the Lions.

“I’m very comfortable,” Fiedler said. “I think I’ve picked up the offense very well. It’s an offense that suits me very well. I think coach [Mike] Heimerdinger and myself are really on the same page the way we look at routes and the way we analyze the game.”

Herm Edwards has been pleased with Fiedler’s learning curve.

“He’s getting a feel for what we wanted to do,” Edwards said yesterday. “He spun the ball real good the day before yesterday in practice.”

Dewayne Robertson was relieved he will not need surgery on his aching left knee following a visit with sports surgeon Dr. James Andrews. If Robertson plays tonight, don’t blink, you may miss him.
